Need help PLEASE!!

I HAVE A QUESTION I JUST BOUGHT MY FIRST NIRTO POWERED CAR, EVERYTHING WENT FINE THROUGH THE BREAK IN PROCESS BUT AFTER THAT I HAVEN'T BEEN ABLE TO GET IT STARTED. wHEN EVER I PULL THE PULL START I GET NOTHING BESIDES SOME LIQUID GAS COMEING OUT MY EXAUST PIPE(NOT A LOT JUST A LITTLE THOUGH) IF ANYONE KNOWS WHAT COULD BE THE PROBLEM PLEASE LET ME KNOW

Are you able to spin the motor with the pullstart if you remove the glow plug and disconnect the fuel line? If you can then maybe what is happening is that the motor is getting too much fuel and cause a hydro lock. This happens when you get too much fuel inside the motor. When the piston goes down it forces too much fuel up into the cylinder so that when the piston tries to go up it can't because the fuel doesn't compress.
